IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 181,623, dated August 29,1876; "application filed February 9, 1876.

, To all whom it may concern:

Be it known that I, EDWIN BARTON, of Flint, in the county of Genesee and State of Michigan, have invented an Improvement in Spring Bed-Bottoms, of which the following is a specification:

The nature of my invention relates to an improvement in spring bed-bottoms of the longitudinal wooden-slat variety, and has for its object to enable the use of a thinner and more elastic slat, which is trussed below by an elastic cord the invention consisting in the peculiar construction of the slat, as more fully hereinafter set forth. v

Figure 1 is a perspective view of the bedbottoni. Fig. 2 is a longitudinal section at m w. Fig.3 is a bottom perspective View of a slat.

In the drawing, A represents a frame adapted to fitinto a bedstead, with an elevated rail at each end, each rail carrying a row of studs, a. B are the slats, all of which are made very thin and flexible, except at the extremities, to one of which is secured a metal clip, b, to engage with a stud, a, and under the other end is secured a spiral spring, 0, with a loop at its outer end to engage with the opposite stud a. c is a truss-block under the middle of each slat, hollowed at the bot tom to form a saddle for a spiral spring, D,

connected at one end by a wire link, 01, with a hook, f, under one end of the slat, and by a similar link to a flanged clip, 6, under the slat, near the spring 0. The end of the link is screw-threaded, and, after passing through the clip, receives a nut, d, by means of which the tension of the spring D may be adjusted, so

1 as to give the slat the required stiffness and tension, thereby making a very elastic bed,

that will conform to the outline of the occupant.

What I claim as my invention is- The slat B, provided with the clip b,.trussblock 0, springs G D, links d 1, clip 0, and hook f, in combination with the studs a, substantially as and for the purpose set forth.

EDWIN BARTON. Witnesses:
